Ultrafast photoinduced electron transfer reactions in supramolecular arrays: From charge separation and storage to molecular switches

Photochemical electron transfer reactions on a picosecond time scale have been studied in two covalently-linked donor-acceptor systems. The first molecule is a chlorophyll-porphyrin-quinone triad that closely mimics photosynthetic charge separation by undergoing picosecond electron transfer in low temperature glasses to yield a radical ion pair that lives for 2 ms and exhibits spin-polarization...

Photoinduced electron transfer in supramolecular donor-acceptor dyads of Zn corrphycene.

Porphyrins have been used by various researchers as important building blocks of photofunctional molecules, while the number of studies on the excitation properties of the structural isomers of porphyrins is small when compared to those of porphyrins. In the present study, photoinduced electron transfer (ET) processes of supramolecular donor-acceptor dyads of 2,3,6,7,11,12,17,18-octaethylcorrph...

Photoinduced electron transfer in alpha-cyclodextrin-based supramolecular dyads: a free-energy-dependence study.

Photoinduced electron transfer (PET) between alpha-cyclodextrin-appended pyrene (PYCD) and a few acceptor molecules was studied in aqueous solutions. The pyrene moiety in PYCD is located above the narrower rim of the alpha-CD and is fully exposed to water. The acceptors are monocyclic organic molecules and, upon dissolution in water in the presence of PYCD, a fraction of the donor-acceptor syst...

Photoinduced Electron Transfer in Ionic Media

Title of Document: PHOTOINDUCED ELECTRON TRANSFER IN IONIC MEDIA Rebecca Cristine Vieira, Doctor of Philosophy, 2008 Directed By: Dr. Daniel E. Falvey, Department of Chemistry and Biochemistry The goal of this research was to explore the use of room temperature ionic liquids (RTILs) and ionic liquids crystals (ILCs) as reaction media for photoinduced electron transfer (PET) processes. Photoindu...
